Description

DETAILED DESCRIPTION OF THE INVENTION The present invention combines plates having several types of required notches with appropriate thickness to form a main body, and a rotor is centripetally arranged in each space inside the main body formed by the notches. The main body is made of a laminated plate in which each of the rotors is placed in contact with a rail that passes through the central part surrounded by the rotors arranged in these spaces so that it can easily slide along the rail. This relates to a slide block that constitutes a section.

For example, in furniture, storage shelves, or relatively small equipment, elements used in sliding or reciprocating mechanisms such as doors, shelves, and drawers that mainly make linear movements are generally rotating bodies such as door wheels, or lubricating elements. Synthetic resin sliders with
As is well known, the frictional resistance is large, so the movement is not smooth, and of course the accuracy is also low, so the purpose has been achieved in the extremely general applications mentioned above. Needless to say, if the amount is small, it can be widely used as a sliding element even in linearly moving parts of furniture and various types of equipment. In particular, if there is no need to supply lubricating oil or other anti-friction agents to the sliding element, it is clear that it is even more effective for locations and applications where the use of oil or fat must be avoided. Therefore, examples of this type of bearings that allow the rotor to rotate freely and guide the shaft in a linear direction are disclosed in Japanese Patent Application Laid-open No. 48-16041 and Japanese Utility Model Application No. 49-29339. . However, in all of these devices, the ball is moved along a guide shaft or guide bar, so it is difficult to improve the smoothness of the means for supporting and rotating the ball. The fact that various proposals have been made regarding means for supporting the ball is proof of its difficulty.

The present invention satisfies the long-desired requirements since the conventional technology has many drawbacks, and provides a slide block with a simple structure, high precision, and minimal sliding resistance, which can be provided at a low cost. This is the purpose.

In the present invention, in the sliding shaft guide body, the main body has at least three rectangular long notches equally distributed radially from the axis of the central guide hole to create a rotating space for the rotor. The formed plate and the rotor support plate each having a rotor support shaft bearing fitting portion formed on both sides of the rotation space are combined to form a rotation space in front and behind the rotation space with the rotor support plate in the center. The required number of plates are laminated so that the plates are positioned, and mounting outer plates with central guide holes are placed on both outer sides of the plates. Hollow fastening is carried out using the mounting holes drilled in multiple locations common to all of these plates. The body is fixedly formed into one body, and an incision portion of an appropriate width is formed from the central guide hole toward the outer periphery, and each space is formed radially from the center by the notch of each plate in the interior of the body. The rotor is supported by a support shaft loosely fitted in a bearing piece provided in a rectangular recess in the intermediate laminated plate portion forming the main body.
One or more rows of the rotor pairs are arranged in the axial direction of the guide hole, and each rotor is brought into contact with a guide rail inserted into the guide hole of the main body so that the cutout of the main body corresponds to the position where the rail support passes. It is.

In the present invention, the outer shape of the laminate is uniformly formed into a required shape, and a part of the outer panel is used as a mounting portion for an object.

Further, in the present invention, a plurality of guide holes are provided by providing cutouts in a desired direction at appropriate intervals in a plate of a desired thickness,
At least three rectangular long notches are equally distributed radially from the axis of the guide hole on both sides of the cutout and on the other side to create a plate with a desired outer shape that forms a rotation space for the rotor. A rotor support plate having rotor support shaft bearing fitting portions formed on both sides of the moving space portion is arranged so that the rotor support plate is located in the center and the rotation space forming plates are located in front and behind the rotor support plate. The required number of sheets are laminated, and outer plates with rail guide holes and cutouts that match the laminated plates are arranged on both sides of the outer plates, and hollow fastening is carried out through mounting holes drilled at multiple locations common to all of these plates. The intermediate laminated plates forming the main body are fixed together to form a main body, and the rotors are respectively installed in the spaces formed radially from the center by the notches of the respective plates adjacent to the respective guide holes of the main body. Each rotor is supported by a support shaft that loosely fits into a bearing piece installed in a square recess in the main body, and each rotor is brought into contact with a guide rail inserted through each guide hole in the main body, and the incision is placed at a position where the rail support passes. It is designed to correspond to

Furthermore, in the present invention, a synthetic resin roller, a metal roller, a small rolling bearing, or a combination of these is used as the rotor, and in any case, the support shaft is inserted into a notch space formed by a laminated plate. Rotatably supported by a bearing formed in the
By selecting the bearing forming material, oil-free lubrication is possible.

Therefore, the guide rail may have a rectangular cross section where the surface that contacts the rotor is flat and a support part and a mounting seat are integrally formed with this, or the support part may have a circular cross section where the contact part with the rotor is formed. A structure in which a mounting seat and a mounting seat are integrally formed, or a structure in which a support portion is connected to a mounting seat at appropriate intervals with respect to a guide portion are adopted.

Embodiments of the present invention will be described in detail below with reference to the drawings. The one shown in FIG. 1 and FIG. The main body 10 is formed by combining a plurality of laminate plates 2 and 3 each having a plurality of thicknesses and having two types of notches, and fastening them together with a plurality of hollow studs 4 and thin studs 8, and forming a main body 10 with a guide hole in the center. A notch space 11 is formed inside toward the rotor 5.
are equally spaced so that their rotating surfaces are positioned radially from the center, and the support shaft 6 of the rotor 5 is held in the recess via a bearing piece 7 so that the rotor 5 can rotate freely.

Each plate constituting the main body 10 can be made of a metal plate or a synthetic resin plate, and an example of its shape is shown in FIG. It is formed into a hexagonal shape with holes, and one side thereof is cut out to the outer periphery to provide an incision 13.
Reference numerals 21 are mounting holes, which are drilled at two positions divided into three equal parts with the center on the circumference drawn with an appropriate radius, and 22 are symmetrically located at appropriate positions inside the corner formed by the cutout 13. This is a drilled rivet hole. What is shown in Fig. 4 is the central laminated plate 3 (rotor support plate) and the central guide hole 1.
2, the cutout 13, the mounting holes 31, and the stud holes 32 are all provided equally on the outer panel 1, and connected to the central guide hole 12 and divided into three, radially from the center with an appropriate width W and a required length. A notch 33 is formed, and a square notch 34 with a stepped tip is formed symmetrically in a direction orthogonal to the long angular notch 33 passing through a point of a required dimension from the center, so that the square notch 34 is exactly aligned with the central guide hole 1.
Cross-shaped notches 35 are formed radially from 2 to 3 directions. Note that the width of the horizontal square notches 34, 34 of each cross-shaped notch 35 is an integral multiple of the thickness of the laminated plate 3. What is shown in FIG. 5 is a double-sided laminated plate 2 (rotation space forming plate), which has the same diameter as the central laminated plate 3 and also has a central guide hole 12, a cutout 13, a mounting hole 21, and a stud hole 22 that are also the same as the outer plate 1. The dimensions of the rectangular notches 23 radially formed into three equal parts from the central guide hole 12 are also made equal to those of the central laminated plate 3. It is preferable that the plates 1, 2, and 3 have the same thickness.

Next, when assembling each of the laminated plates, three central laminated plates 3, two laminated plates 2 on both sides before and after the central laminated plates 3, and each cutout 13 and each rectangular notch 2 are inserted.
3, 33 and mounting holes 21, 31, rivet holes 22, 3
2 are aligned and stacked, and in this way, rectangular notches 23,
A longitudinal space 11 is formed by 33, and in the center thereof, a rectangular recess 9 is symmetrically formed with laterally symmetrical rectangular notches 34, 34, which are perpendicular to each other. The rectangular recesses 9, 9 are configured so that the cross section perpendicular to the axial direction thereof is square, and a bearing piece 7 that fits into the rectangular recess 9 is fitted, and the bearing piece 7 rotates. The rotors 5 are each disposed within the space 11 so that the support shaft 6 of the child 5 can be accurately and rotatably supported. The rotor 5 is made of synthetic resin or a small rolling bearing.

As shown in FIG. 2, the guide rail 15 has a hexagonal guide section and a leg section of an appropriate length forming a support section 15'' on one side, and a flat mounting plate is attached to the end of the leg section. It is made into one piece with a seat 15a, and this is laid and fixed at the desired location for the required length.This guide rail is made by attaching leg pieces at appropriate intervals to one side of a hexagonal bar by welding or the like and connecting it to the mounting seat. This type of structure is suitable for a tall rail in which the head (guide portion) of the rail is relatively far from the mounting seat.

When the slide block configured as described above is used, for example, as a sliding door or a movable table, a recess into which the main body 10 can be fitted is formed at the side end of the target moving object, and the main body 10 is inserted as shown in FIG. 10 fastening hollow studs 4
The bolts 16 are tightened using the inside of the guide rail 15, and the mounting seat of the guide rail 15 is fixed to a metal fitting, nail, etc. as appropriate on the stationary body side, and the required length is provided.The guide portion 15' of the guide rail 15 is attached to the slide block A If it is inserted into the central guide hole 12 of the guide rail 15 through the cutout 13, the guide portion 15' top surface and slanted lower surface of the guide rail 15,
The circumferential surfaces of each rotor 5 disposed in the main body 10 are in equal contact (the dimensions of this abutting relationship are set in advance so that the dimensions of the guide portion of the guide rail and the dimensions of the contact corresponding to the rotor circumferential surface of the block match). ), the guide portion 15' of the guide rail 15 is connected to the three rotors 5
It slides along the rail while being held by the object, and therefore, if the required number of slide blocks A are correctly installed on the side of the object to be moved, smooth and accurate movement can be performed without coming off or floating. It is. At this time, the rotor 5 support shaft 6 disposed in the space 11 in the main body 10 is supported by the bearing piece 7 installed in the rectangular recess 9 formed by the laminated plates as described above. Therefore, accuracy is expected even though the main body is made of laminated plates.

In this way, the slide block of the present invention slides while holding the so-called head of the guide rail by the rotor installed therein, and since it moves by the rolling motion of the rotor, each rotor By making the contact state between the guide part and the guide part precise, highly accurate movement operation is possible, and therefore it is suitable for use as a moving body for equipment and instruments that avoid generation of vibration and noise. It is also highly effective.

Further, according to the spirit of the present invention, the outer shape of the slide block main body is formed into a rectangular shape as shown in FIGS. A mounting seat 1a is formed by bending the side opposite to the cutout 13' on the outer panel 1', using the same long-angled notch and rectangular depression forming part as in the example. The guide rail 15 is formed by being integrally fastened together with the other laminates 2 and 3 using hollow studs 4 through common mounting holes drilled at four locations, and the guide rail 15 has its guide portion 15' as in the previous embodiment.
As shown in the figure, each rotor 5 is made to abut against and slide.

With this configuration, it is possible to use the mounting hole provided in the mounting seat 1a to attach it to a moving object like a conventional door wheel without having to fit it into a circular hole. Other effects are the same as those described above. Of course, it is also possible to use a device formed in such a rectangular shape without having a mounting seat on the outer panel as in the above embodiment, and in this case, the fastening hollow rivet hole may be used as the hole for mounting.

The above description has been about a single type, but according to the spirit of the present invention, a single plate has a plurality of guide holes and cutouts radially from the center to form a space for installing the rotor. It is also possible to construct a so-called double-row guide hole type by combining a plurality of guide holes provided for each guide hole in the same manner as described above.
A specific example of this method will be described in detail with reference to the drawings. As shown in FIGS. 9 and 10, the guide holes 12 are arranged at two locations at appropriate intervals, and the incisions 13 are provided in opposite directions in the longitudinal direction. It is a slide block B, and a plurality of notches and two types of notches are provided with an appropriate thickness between the left and right outer plates 41, 41, which have a guide hole 12, a cutout 13, and a required number of holes for fastening at two locations. The formed laminated plates 42 and 43 are combined and fastened together with a plurality of hollow studs 4 and thin studs 8 to form a main body 40, and each guide hole 12 has a cutout space inside toward its center. A portion 11 is formed in which a plurality of rotors 5 are arranged equally so that their rotating surfaces are positioned radially from the center, and the rotors 5 are rotatably supported.

Each plate constituting the main body 40, especially the intermediate laminated plate 43, is provided with a rectangular notch 34 for each guide hole 12 similar to that of the single type, and both side laminated plates 42 are similarly provided with the same square notch 34 as the single type. Like the single type, a rectangular notch 22 is provided for each guide hole 12. When assembling the 433 intermediate laminates, two laminates 42 on both sides are stacked on each other, and outer panels 41 are placed on both sides.
Stack them one on top of the other and fasten them together using hollow rivets 4 in the mounting holes and thin rivets 8 in the rivet holes,
Bearing pieces 7 are fitted into the rectangular recesses 9 formed in the intermediate laminated plate 43, and the support shaft 6 is inserted through the bearing pieces 7.
Similarly to the embodiment described above, rotors 5 are rotatably installed in each space 11, and in this type, two guide holes are provided and a pair of rotors is provided surrounding the guide holes. The guide rails 15 are respectively inserted into the guide holes 12 through the cutouts 13, and the two guide rails 15, 1
5 so that it can be slid freely. Of course, the same guide rails 15 as in the previous embodiment are used, but if necessary, even if the guide portions 15' are round, they can be held in position with respect to each other by two guide rails. I can't shake it.

If this type of slide block is used for a part that moves in a cantilevered manner, such as a drawer, it will be guided in a stable manner against both guide rails, allowing for highly accurate movement. can be obtained easily and is even more effective.

It goes without saying that with this type of slide block, the orientation of the cutout relative to the guide hole can be arbitrarily selected depending on the mounting position of the guide rail and the correspondence between the block and the guide rail. Instead, you can use one with its orientation changed if necessary. The same applies to the overall external shape and dimensions.

Furthermore, according to the above idea, even if two of the single type units are arranged at appropriate intervals and two support plates 17 corresponding to the outer panel of the specific example are sandwiched and fixed from both outside sides, As shown in FIG. 11, the same effects as in the specific example described above can be obtained, and this configuration has the advantage that the distance between the guide rails can be increased.

Further, by providing two or more guide parts on one slide block and arbitrarily setting the outer shape of this block and the arrangement of the guide parts, its uses can be further expanded.

Furthermore, when a plurality of guide holes are provided, as shown in FIG. 12, one is provided with the cutout 13 as described above, and the other is provided with only the guide hole 12, and each has a rotor as described above inside. Alternatively, it may be effective to insert the legged guide rail 15 into the guide hole 12 side with the incision 13 and insert the guide shaft 18 into the guide hole 12 side for guiding movement. .

As described above, according to the present invention, at least three types of plate materials having a predetermined thickness and cutouts in a desired shape are formed, and the required number of plates are combined and laminated in a predetermined order. By fastening them together, the guide rail, which is inserted through the guide hole provided at the center or at a desired position and the cutout communicating with the guide hole, is supported by a bearing piece installed in the rectangular recess inside the main body. By abutting the rotor on the shaft, smooth sliding with high dimensional accuracy is achieved. In particular, by holding the guide rail with the rotor, smooth and accurate movement is achieved while rolling. It can be used for equipment and tools that require sliding or reciprocating motion, allowing movement with extremely low resistance, such as drawers, doors, etc.
In addition, by using it as a relatively small-sized moving element, it was possible to obtain something that achieved unprecedented effects, making it a useful item that can be used for a variety of purposes. In addition, since it can be manufactured by punching a plate, it is easy to mass-produce and can provide inexpensive and highly accurate products, making it highly practical.
